SCSI and I/O     8-75
Firmware Upgrade Failures:
 
• Wrong firmware tape - The tape will be ejected within 1/2 to 1 minute of activity and no update will 
have been done. (Match tape part number to product model number.)
 
• Firmware tape used up - The tape will automatically be re-formatted by the drive as a normal data tape 
and will no longer react as a firmware tape (This will occur after 200 passes).
 
• Firmware tape write protected - The tape will be ejected and no update will be done.
 
• Process interrupted at crucial point - If a power interruption occurs or activity on the SCSI bus 
interferes, a DEAD DRIVE will be created.
 
Verify the upgrade by using appropriate diagnostic or utility. (SCSIDDS Interactive command REVision)
